Rework highlighting management of cursor position

Move the whole responsibility of making the cursor visible to the
window, removing cursor_pos from the display setup and resolving
the cursor location by finding it in the display buffer afterwards.

This simplifies hightlighters' do_compute_display_setup as they do
not need to compute the cursor location. Highlighting may run on
more lines than necessary after this change but this should be a
minor performance hit.
